Objective To determine the level of interleukin (IL)-10 in sera and culture supernatants of CD4+CD25+T cells from children with atopic dermatitis (AD),and to evaluate its relationship with clinical course and severity of AD.Methods Totally,46 children with AD and 31 healthy controls were included in the study.All the patients were divided into 3 groups,i.e.,mild (n =10),moderate (n =16) and severe (n =20) group,according to severity scoring of atopic dermatitis (SCORAD) score.Venous blood samples were obtained from the patients and healthy controls.CD4+CD25+ regulatory T cells were separated from the blood samples by magnetic cell sorting (MACS) system in two steps and cultured in vitro.Enzyme linked immunosorbent assay (ELISA) was conducted to quantify the level of IL-10 in sera and culture supernatants of CD4+CD25 + T cells from these subjects.Analysis of variance was carried out to compare the level of supematant and serum IL-10 between the patients and controls,and Pearson correlation analysis to assess the relationship between the level of IL-10 and SCORAD score.Results The patients with mild,moderate and severe AD showed a similar serum IL-10 level compared with the healthy controls ((43.10 ± 25.07) pg/ml,(68.40 ± 36.65) pg/ml and (55.55 ± 41.97) pg/ml vs.(58.27 ± 36.84) pg/ml,all P ＞ 0.05).The level of supernatant IL-10 secreted by CD4+CD25+ T cells from the controls was significantly higher than that from the patients with severe AD ((55.15 ± 11.15) pg/ml vs.(27.25 ± 7.01) pg/ml,P ＜ 0.05),but similar to that from the patients with mild and moderate AD ((52.96 ± 11.69) pg/ml and (49.86 ± 9.18) pg/ml,respectively,both P ＞ 0.05).The level of secreted IL-10 was negatively correlated with SCORAD score (r =－0.757,P ＜ 0.01),whereas the serum level of IL-10 showed no statistical correlation with SCORAD score.Conclusion CD4+CD25+ T cells and IL-10 may be implicated in the development of AD.

ObjectiveTo evaluate the roles of imbalance between peripheral blood T helper 17 (Th17) cells and CD4+CD25+ regulatory T(Treg) cells in the pathogenesis of atopic dermatitis (AD).Methods Peripheral blood samples were obtained from 52 patients with AD aged 2-14 years and 30 age- and sex-matched healthy controls.Flow cytometry was performed to detect the percentage of Th17 cells and Treg cells in peripheral blood.Meanwhile,enzyme linked immunosorbent assay(ELISA) was carried out to detect the serumlevel of interleukin (IL)-6 and transforming growth factor (TGF)-β1.Results The children with AD showed a higher percentage of Th17 cells but a lower percentage of Treg cells in CD3+ T cells compared with the controls (( 1.20 ± 0.41 )％ vs.(0.54 ± 0.28)％,t =2.58,P ＜ 0.05; (2.29 ± 0.67)％ vs.(5.95 ± 0.45)％,t =15.23,P ＜ 0.01 ).Moreover,the serum level of IL-6 was significantly higher,while that of TGF-β1 was lower in patients with AD than in the controls ((5.12 ± 0.45) ng/L vs.(3.89 ± 0.38) ng/L,t =2.59,P＜ 0.05; (57.65 ± 10.78) ng/L vs. (81.18 ± 7.78) ng/L,t =5.41,P ＜ 0.01 ).ConclusionsChildren with AD experience a change in the percentage of Thl7 cells and Treg cells in peripheral blood as well as in the serum level of IL-6 and TGF-β1,and the imbalance between Th17 cells and Treg cells in peripheral blood may contribute to the development of AD.

[Objective]To discuss the pathogenesis,hierarchy,treatment and medication rules of deficiency of Yang with hyperactivity of Yin syndrome in Treatise on Febrile Diseases.[Methods]Combining with the medical theory of later physicians,this paper clarifies the pathogenesis and syndrome of deficiency of Yang with hyperactivity of Yin syndrome,explains the mechanism of Yang deficiency and Yin excess syndrome from the perspective of pathophysiology.This paper also analyzes the differences among the various versions of the text of the Shaoyin Chapter including the variations in disease location,the pathogen nature,stomach Qi and body fluid,and inducts the implicit therapeutic principles in the Shaoyin Chapter.[Results]The principle of differentiation and treatment for deficiency of Yang with hyperactivity of Yin syndrome is"protecting stomach Qi and preserving body fluids",which can be subdivided into Taiyin damp earth disease,Shaoyin monarch fire disease,and Jueyin wind wood disease.Through careful observation,questioning,smelling and palpation,combined with the pathological and physiological basis of modern medicine,it can accurately diagnose deficiency of Yang with hyperactivity of Yin syndrome.Shaoyin plays a crucial role in Treatise on Febrile Diseases.The structure of the Shaoyin Chapter is well-organized and can dynamically reflect the changes in the pathogenesis of Shaoyin syndrome,the combination of Shaoyin and Taiyin or Jueyin,or the tri-coordination syndrome of these location.From the text,it can be inferred that the location of the disease begins on the surface and gradually extends to the interior.The treatment methods will include moxibustion,warming the meridians,warming Yang and dredging Yang.The severity of the illness and the presence of phlegm-fluid determine the treatment,which may involve dispersing cold,dispersing fluids,and promoting urination.The degree of exhaustion of bodily fluids may require either reviving Yang for resuscitation or nourishing Yin.[Conclusion]From a pathological and physiological perspective,the mechanisms behind the changes in the primary symptoms of traditional Chinese medicine can be explained.When treating deficiency of Yang with hyperactivity of Yin syndrome,the selection of herbal prescriptions should be based on factors such as the disease location,the pathogen nature,stomach Qi and body fluids.The treatment principles for deficiency of Yang with hyperactivity of Yin syndrome have instructive significance for the treatment of other syndromes as well.

OBJECTIVETo establish the differential templates of the skeletal profiles for Shanghainese with normal occlusion in early permanent dentition.

METHODS71 lateral cephalometric radiographs of subjects with normal occlusion in early permanent dentition, aged from 11 - 15 years (37 females and 34 males) were traced. 23 skeletal landmarks were identified on the tracings, which afterwards were scanned on the computer. An x-y coordinate system was established: the tracing superimposed on sella rotated 7 degrees down from the sella-nasion line as the x axis and the vertical line through sella perpendicular to the x axis as the y axis. A special length/depth ratio was designed. The length/depth ratio of each graph were calculated. Steiner analysis was applied to check the difference between genders.

RESULTSThere was no difference between genders. The tracings were divided into three categories: short face, normal face and long face according to the mean and standard deviation of the ratio. The three types of tracings were superimposed on the x axis with sella registered. Three templates were created.

CONCLUSIONSThe differences were apparent when the three templates were superimposed.

Macrophages are widely distributed immune cells that contribute to tissue homeostasis. Human THP-1 cells have been widely used in various macrophage-associated studies, especially those involving pro-inflammatory M1 and anti-inflammatory M2 phenotypes. However, the molecular characterization of four M2 subtypes (M2a, M2b, M2c, and M2d) derived from THP-1 has not been fully investigated. In this study, we systematically analyzed the protein expression profiles of human THP-1-derived macrophages (M0, M1, M2a, M2b, M2c, and M2d) using quantitative proteomics approaches. The commonly and specially regulated proteins of the four M2 subtypes and their potential biological functions were further investigated. The results showed that M2a and M2b, and M2c and M2d have very similar protein expression profiles. These data could serve as an important resource for studies of macrophages using THP-1 cells, and provide a reference to distinguish different M2 subtypes in macrophage-associated diseases for subsequent clinical research.

OBJECTIVE: To study the correlation of CD44 with epithelial-mesenchymal transition(EMT) and metastasis in nasopharyngeal cancer cells, and explore the possible mechanism of CD44 regulates EMT and metastasis in nasopharyngeal cancer cells. METHOD: The CD44 and EMT-associated proteins in 5-8F and 6-10B nasopharyngeal cancer cell lines were assayed by Western blotting. The erasion trace test was performed to observe the migratory ability of 5-8F and 6-10B nasopharyngeal cancer cells. Using lipid-mediated DNA transfection technique, the low metastatic nasopharyngeal cancer cells 6-10B were transfected in vitro with plasmid which contained CD44 gene, and then new nasopharyngeal cancer cells were obtained. The CD44 and EMT-associated proteins in 6-10B, empty vector transfected and CD44-transfected cells were assayed by Western blotting. The erasion trace test was performed to observe the alteration of migratory ability of nasopharyngeal cancer cells before and after CD44 transfection. RESULT: The expression of CD44 and EMT-associated protein MMP-9 in 5-8F was higher than that in 6-10B, but EMT-associated protein E-Cadherin in 5-8F was lower than that in 6-10B. The migratory ability of 5-8F was higher than that of 6-10B. The expression of CD44 and MMP-9 were significantly higher in the CD44-transfected nasopharyngeal cancer cells than in the control groups. Compared with control groups, the migratory ability of CD44-transfected nasopharyngeal cancer cells was significantly increased. CONCLUSION CD44 positively regulates the metastatic ability of nasopharyngeal cancer cells, which is relevant to the process of EMT.
